1. A battery pack, comprising:
- a rechargeable battery module; and
a battery management system for controlling charging and/or discharging of the battery module, wherein;
the battery module includes a substantially linear charging and discharging voltage-time profile within at least part of the charging and discharging cycle of the battery module, and the battery management system is configured to calculate a state of charge of the battery module by using linear charging and/or discharging characteristics of the battery module; and
wherein the battery management system is arranged to calculate a second state of charge of the battery module after a time period of charging or discharging by determining a first state of charge of the battery module and then using the linear charging and/or discharging characteristics of the battery module.
